The invention relates to the technical field of livestock breeding, and discloses a feeding device wider in feeding range. The feeding device comprises a base mounted on the ground, the upper surfaceof the base is fixedly connected with a conveying belt, the right side face of the base is fixedly connected with a supporting plate, and the upper surface of the supporting plate is fixedly connectedwith an extending plate. According to the feeding device wider in feeding range, a first telescopic rod cooperates with a connecting plate, a storage groove, a first spring, a piston and a scraper, and therefore the inner wall of a storage bucket can be cleaned; a winding groove cooperates with a pop-up groove, a fixed rod, a fixed ring, a second spring, a first mounting disc, a first discharginghole, a second mounting disc, a second discharging hole, a powerful fan and a rope, the feeding range of feed can be wider, the feed can be put more evenly, and it is avoided that due to uneven distribution of the feed, the fish growth degree difference is large; the feed can be prevented from being accumulated in the storage bucket for a long time, fishes fall ill due to the feed going bad, andbenefits are guaranteed.
